Question

difference between true suspension and colloidal solution.​

Answer 1

Answer:

True solution

(i) A true solution is a homogeneous mixture of two or more than two substances.

(ii) In a true solution, solute cannot be seen even with a microscope.

(iii) In a true solution, the size of particles is about 10-10 m.

(iv) The constituents of a true solution cannot be separated by filtration.

Colloid

(i) A colloid is a homogeneous-looking, but heterogeneous-mixture.

(ii) In a colloid, the particles can be seen only with a powerful microscope.

(iii) In a colloid, the size of particle is between 10-7  10-9 m.

(iv) The constituents of a colloid cannot be separated by filtration.

Suspension

(i) A suspension is a heterogeneous mixture of a solid dispersed in a liquid, or gas.

(ii) In a suspension, the particles can be seen with the naked eyes.

(iii) In a suspension, the size or particle is bigger than 10-7 m.

(v) The constituents of a suspension can be separated by ordinary filtration.

Answer 2

Explanation:

The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque.
